Steps to Hearing:* Vibrations move through the outer ear canal and vibrate the eardrum. The eardrum passes its energy through a chain of three tiny bones, the anvil, hammer, and stirrup, in the middle of the ear. The anvil, hammer, and stirrup pass the energy onto the cochlea. The vibrations activate hair cells and fluid inside the cochlea. Electrical signals are sent to the brain through the auditory nerve.
